我对apache+php的方式不太了解,我现在升级了PHP到5.3,但是我的apache运行的php还是5.2,现在不知道如何修改。我php和apache都是编译安装的。
我的apache配置文件里LoadModule为如下配置:
LoadModule php5_module modules/libphp5.so

把原来Apache的modules下libphp5.so备份成libphp5.2.so。
假如你的Apache编译安装在/png/httpd/2.2.25。
PHP在执行configure脚本时加入参数--with-apxs2=/png/httpd/2.2.25/bin/apxs即可调用apxs生成模块/png/httpd/2.2.25/modules/libphp5.so,注:编译PHP的时候必须指定apxs才能编译出Apache模块libphp5.so
新手来回答哈,找到你的apache安装目录,在安装目录下找到conf/httpd.conf
这是apahche的配置文件,打开配置文件找到LoadModule模块
在后面添加 LoadModule php5_module "D:/CuminSer/php/php5apache2_2.dll" 双引号中的是你的实际PHP加载apache路径,你就可以换你的5.3的PHP版本路径apache的DLL
ini文件也要换你的5.3路径
修改保存,然会重启apache服务

Session regeneration refers to generating a new session ID and invalidating the old ID when the user performs sensitive operations in case of session fixed attacks. The implementation steps include: 1. Detect sensitive operations, 2. Generate new session ID, 3. Destroy old session ID, 4. Update user-side session information.

PHP sessions have a significant impact on application performance. Optimization methods include: 1. Use a database to store session data to improve response speed; 2. Reduce the use of session data and only store necessary information; 3. Use a non-blocking session processor to improve concurrency capabilities; 4. Adjust the session expiration time to balance user experience and server burden; 5. Use persistent sessions to reduce the number of data read and write times.

The security of PHP sessions can be achieved through the following measures: 1. Use session_regenerate_id() to regenerate the session ID when the user logs in or is an important operation. 2. Encrypt the transmission session ID through the HTTPS protocol. 3. Use session_save_path() to specify the secure directory to store session data and set permissions correctly.
